Bushings
The most reliable solution to insulate your transformer
Our bushings are the perfect solution for insulating your transformer, thanks to the high level of application fit and easy handling. Standardized design up to 52 kV and production expertise developed over many years represent the best value-for-price guarantee in the market. To meet specific customer requirements, we can offer a variety of suitable options, whether by replacing an existing bushing and modify certain parameters or developing and completely redesigning a bushing to meet your exact demands.
